Draw the graphs of the equations, x = 3, x = 5 and 2x - y - 4 = 0. Find the area of the quadrilateral formed by the lines and the X - axis.
Given equation of lines x = 3, x = 5 and 2x-y-4 = 0.
Now, the table for line 2x - y - 4 = 0
for x = 0, y = - 4 and for y = 0, x = 2
0 | 2 | |
y | - 4 | 0 |
Points | P | Q |
Draw the points P(0, - 4) and Q(2, 0) and join these points and form a line PQ also draw the lines x = 3 and x = 5.
Area of Quadrileral ABCD = 1/2×(distance between parallel lines)
[since, quadrilateral ABCD is a trapezium]
{since AB = OB-OA = 5-3 = 2, AD = 2 and BC = 6}
= 8 sq units
